Case Study Questions on Acids Bases and Salts
Questions
Question 1:
Read the given passage below and answer the question:
Priya’s father was suffering from severe stomach pain. He was showing symptoms of heartburn and indigestion. He consulted a doctor who told him that he was suffering from acidity and advised him to take an antacid tablet after each meal. Priya’s father followed the advice strictly and was cured.
Q.1. Which acid is produced in our stomach?
(a) Sulphuric acid
(b) Hydrochloric acid
(c) Nitric acid
(d) Phosphoric acid
Difficulty Level: Easy
Ans. Option (b) is correct
Explanation: The inner lining of the stomach secretes hydrochloric acid. It provides the acidic
medium for digestion of food however, if the amount of acid produced in the stomach is exceeds then it causes indigestion and burning sensation.
Q.2. Antacids contain:
(a) acid
(b) base
(c) salt
(d) both (a) and (b)
Difficulty Level: Easy
Ans. Option (b) is correct.
Explanation: Antacids are medicines which contain a base. They help to neutralise the excess acid present in the stomach.
Q.3. Milk of magnesia is an antacid which contains:
(a) magnesium chloride
(b) magnesium phosphate
(c) magnesium hydroxide
(d) magnesium nitrate
Difficulty Level: Difficult
Ans. Option (c) is correct.
Explanation: Milk of magnesia is used as an antacid. It contains magnesium hydroxide which neutralises the effect of excessive acid.
Q.4. Explain how an antacid tablet gave relief to Priya’s father.
Difficulty Level: Difficult
Ans. Hydrochloric acid is produced in our stomach which helps in digestion. However, when too much of acid produces, it causes indigestion. Antacid tablet contains base. When a tablet is taken, the base neutralise the effect of acid and gives relief from the problem of acidity.
Q.5. Is a glass of lemon water gives relief in indigestion? Why?
Difficulty Level: Medium
Ans. No, drinking lemon water during indigestion will not give relief because lemon juice is acidic in nature. Drinking lemonade may worsen the condition of indigestion.
